Recently we proposed a phase field model to describe Marangoni convection in a compressible fluid of van der Waals type far from criticality [Eur. Phys. J. B 44, 101 (2005)]. The model previously developed for a two-layer geometry is now extended to drops and bubbles. A randomly distributed initial density evolves towards phase separation and single droplet formation. For a two-component liquid-liquid system we report on numerical simulations for drop Marangoni migration in a vertical thermal gradient.
最近，我们提出了一个相场模型来描述远离临界点的范德瓦尔斯型可压缩流体中的马兰戈尼对流[《欧洲物理杂志B》44, 101 (2005)]。之前为两层几何结构开发的模型现在扩展到了液滴和气泡。随机分布的初始密度朝着相分离和单个液滴形成的方向演化。对于双组分液-液系统，我们报告了在垂直热梯度中液滴马兰戈尼迁移的数值模拟结果。
